COMBINED LAND ROLLER AND OORRYUGATOR.

SPECIFICATION forming part of Letters Patent No. 739,307, dated September 22, 1903.

Application filed January 22, 1902i. Serial No. 90.744. V(No model.) i

To @ZZ whom t may con/cern:

Beit known that I, EUGENE H. GE'UBB, a citizen of the United States, residing at Carbondale,in the county of Garfield and Stateof Colorado, have invented certain new and useful Improvements in a Combined Land Roller and Corrugator; and I do hereby declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the art to which it appertains -to make and use the same.

Myinvention relates to improvementsin machines for treating land preparatory to planting or seeding, whereby the surface soil after being pulverized is pressed down or firmed, so that it may closely cover the seed and prevent too rapid evaporation, and in which provision is made for the formation of shallow trenches which are adapted to receive, distribute, and

convey the water received from nearby irrigating canals and ditches.

The especial objects of my invention are to produce a machine of the class described which may bereadily converted from a trenchforming apparatus into a land-roller of ordinary functions; which will form shallow trenches, the bottom and sides of which will be iirmly pressed, thus facilitating the flow of the irrigating streams through the trenches,

but at the same time permitting the water to seep through the sides and thus spread out laterally below the surface of the adjacent ridges of soil; which will form the trenches of uniform depth where the surface is rolling or irregular in contour; in which the depth of the trenches may be regulated, and in which the number of trenches formed by each machine of a given width may be varied as may invention;

suitably-shaped metaly bars bent to the rectangular form shown. In the side bars of the 1 frame suitable bearings are provided for the aXle,`upon which the rollers are loosely mounted. To the center of the rear cross-bar of the frame is secured a post G, on the upper end of which the drivers seat G is secured in any suitable manner.

' The rollers B B are metal cylinders having plane surfaces and provided at each end with the usual heads b2, in which the roller-axle bearings are bored or ca st. Secured to the face of the rollers by bolts c are metal fianges C, which, in cooperation with parts to be described, form the shallow trenches above referred to. The iiangesare preferably formed in hollow segmental'sections, las shown in Fig. 3, and incross-section are trunco-conio, with inwardly-turned edges c2, which rest on the face ofthe rollers in the manner shown in Fig. 4C. The attaching-bolts pass through suitablev holes in the apex of the ilangesections and into threaded holes in the rollers. These holes may be arranged in as many annular series as it maybe desired to have flanges on the roller, or there may be formed extra sets of holes for altering the spacing of the flanges or attaching additional flanges. In the drawings I have shown five flanges, with the middle flange secured near the inner edge of the roller B', so thatv it overlaps the adjacent edge of the roller B, thus preventing the soil from entering the opening between said edges. When the flange-sections are fitted together about a roller, they form annular projecting truncoconic collars having`- their bases or widest portions resting on the surface of the rollers.

The rollers are formed in two sections, as indicated by the dotted line in Fig. l, but it is manifest they may be made in three sections, as with the Ordinary land-rollers, the purpose of such formation being that it facilitates turning corners.

y To displace some of the soil, Aso asto facilitate the work of the flanges in forming the trenches, I provide aseries of shovels d', having eacha stem donwhich is mounted a spiral spring d2, one end ofvwhich bears against the squared upper end of the shovel. The

f', secured to the frame, and by the levers F,

which are pivoted on the frame. The straps are slotted, as shown, an d are secu red by screwbolts f2, which pass through the slots and into the frame, adj ustability being eiiected by simply loosening' the bolt head from the strap and raising or lowering the strap, whereby the front edge ol' the bar D, to which the lower ends of the straps are secured, will be raised or lowered. The levers F are pivoted 011 the outside of the side bars of the frame, as at f3, and have their rear ends joined bya cross-bar E and their forward ends bent downwardly and pivoted on the ends of the shovel-carrying bar D near its rear edge. The lever-bar E is in position convenient for operation by the driver, and when depressed will raise the forward end of the levers F, which will correspondingly raise or tilt the rear edge of the bai' D, thus throwing rearwardly and upwardly the shovels, as indicated by dotted lines in Fig. 2, whereby they will run shallow or deep, as may be desired. To provide for the passage of the shovels over stones and at the same time hold them to their work in making a furrow, I arrange the springs (Z2 between the top of the shovels and the under side of the bar D, the tension of the springs being such that they will yield to any obstinate obstruction which cannot be thown aside or removed by the shovel, but under all normal conditions will hold the point of the shovels in the ground.

Vhen it is desired to use the machine simply as a land-roller, the screw-bolts c are removed and the flange-sections detached, when the rollers present a practically unbroken surface. v

Having thus described my invention, what I claim as new, and desire to obtain by Letters Patent, is-

l. A land roller and eorrugator, divided into two or more sections, hollow llanges truneo-conic in cross-section, formed in segmental seetions and detaehably secured to the surface of the roller, one or more of said flanges overlapping the joint or joints between the sections of the rollers, whereby an unbroken surface is presented to the land, substantially as set forth.

2. A land roller and corrugator, formed in l'flVO Ol 111016 SeClilOIlS 1110l111li0d O11 it 00111111011v axle, a frame supporting said axle, projecting annular flan ges detachably secured to the snrface of the roller, and one or more of said anges positioned to cover the joints between the roller-sections, plows suspended from said frame and arranged in line with said liangcs,

and means for raising and lowering said plows. l

In testimony whereof I afX my signature in presence ol' two witnesses.

EUGENE Il. GRUBB.
